It is a bit difficult for me to answer that question in my second language. Allow me to respond in English.
The validation process is fully independent of what the state of design does with regard to their certification, and it allows us for a continuum of involvement. We can choose, depending on how a state of design certifies. When we look at that certification, we can feel fairly assured with the information that's being presented to us. We can have a minimal level of involvement if we see there is very little risk that we've determined as part of that certification. On the other end, it also permits us to have a very significant involvement in validating the work of that state of design. A perfect example of that is the ongoing work of the 737 Max right now. We've chosen, as a validating state, to conduct our own flight test, as opposed to observing or taking the information from the FAA's flight test. We have chosen to observe or actively participate in a number of the different testing phases, as well as looking in more detail at a number of different envelopes within the certification process that the FAA is undertaking.
That's what this process allows us. The process itself does allow for the flexibility of the validating state to determine how involved it wants to be.
